分析了YL25型轮胎压路机后轮系统的工作原理,设计选择了后轮系统的传动方案,而且同时确定了后轮轮胎设计、链轮链条设计、制动器设计、差速器设计、后轮轴设计以及对后轮轴的强

摘要要轮胎压路机作为压实机械中极其重要的一类,对路面具有搓揉压实作用,克服了钢轨压路机压实不均匀、容易压碎路面、表面容易出现裂纹等缺陷,在各种公路、大坝、机场港口跑道和体育场等大型工程项目中广泛的使用,它能够改善路面的表层质量,而且还能够另路面的使用的年限得以增加。目前,随着经济建设的飞快发展,道路建设也不断发展,轮胎压路机已成为道路工程中必不可缺的施工机械。本文对徐工集团的YL25型压路机后轮系统进行了创新设计以及改进,研究了国际市场上轮胎压路机的现状以及发展前景,分析了YL25型轮胎压路机后轮系统的工作原理,设计选择了后轮系统的传动方案,而且同时确定了后轮轮胎设计、链轮链条设计、制动器设计、差速器设计、后轮轴设计以及对后轮轴的强度进行强度计算与校核。使用CAD绘制了相关的原理图、零件图以及装配图等。最终完成了对YL25型轮胎压路机后轮系统的设计。41056

Design Back Wheel System of the YL25 Tire Toller
Abstract Tire roller is still a very important role in compaction machinery that belongs to static effect roller, compaction on the road with a rub, and overcome the uneven compaction of roller rails, easily crushed pavement,surface prone to cracks and other defects,and it was widely used in a variety of roads, dams, airports, ports and runways stadiums and other large projects, it is possible to improve the surface quality of the road, but also to use another road of life is increased. At present, with the fast development of economic construction, road construction also continues to develop, tire roller has become a indispensable part in road engineering construction machinery. This paper focuses on back wheel system of the YL25 tire roller of Xugong group that has been improved and innovative design, analyzed the current situation and development trend of domestic and foreign tire roller,studied the working principle of back wheel system of the YL25 tire roller,designed and chosen the back wheel drive programs and was carried on back wheel tire design, chain sprocket design, brakes design, differential design and back wheel axle design, and carried on calculation and check into the strength of the back wheel axle strength . The related parts drawing and assembly drawing are also drawn with the use of CAD. Finally, completed the design of back wheel system of the YL25 tire roller .
